(CNN Money) -- The head of the AFL-CIO has stepped down from the White House's manufacturing council after President Trump doubled down on his position that violence in Charlottesville was perpetrated by many sides at a press conference Tuesday.

Richard Trumka said in a statement posted on Twitter that he "cannot sit on a council for a President who tolerates bigotry and domestic terrorism" and called Tuesday's remarks "the last straw."

"President Trump's remarks today repudiate his forced remarks yesterday about the KKK and neo-Nazis. We must resign on behalf of America's working people, who reject all notions of legitimacy of these bigoted groups," he said.
